When I am trying to print or save as pdf form print view I am getting the below Uncaught Server Error.

Traceback (most recent call last):

Kindly help.Thank You

Which Form? Can you provide more information for us to replicate?

Cannot replicate in Quotation and Sales Invoice.

Thank you @netchampfaris
In custom doctype when I am put date value in title filed then only this error is showing.Now I am changed my title form date to string type field.
